Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Puff Paste
Ingredients
Directions
Make the paste
Place the flour on a clean surface and make a well in the center.
Add the salt and water, mixing until a smooth paste forms that doesn't stick to your hands.
Roll out the paste to about 1 inch thick and place the butter in the center.
Fold the edges of the paste over the butter.
Laminate and shape
Roll out the paste as thin as possible.
Fold the paste over in thirds to create layers.
Let the paste rest for a few minutes.
Repeat the rolling and folding process three or four times.
Shape the paste into a lump.
Roll it out to your desired thickness.

Shared aroma: isobutyraldehyde (malty, green).
Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fine flour
- Forms the structure of the paste that holds the layers together.
- Butter
- Creates separate fat layers that turn steamy in the oven, lifting the pastry into flaky layers.
- Water
- Combines with the flour to form the dough and develops its elasticity.
The step that matters
Keeping the butter layers intact during rolling. If the butter softens too much or breaks through the dough, the layers blend together instead of separating. Rolling thin, folding and resting the paste keeps the fat in distinct sheets, which is what makes puff pastry rise and flake.
